Hi, We did a PoC at Orange and encountered some difficulties in configurating federation. Can you check that placements targets are identical on each zone? brgds De : ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
De la part de WD_Hwang@xxxxxxxxxxx Hi Craig, I am testing the federated gateway of 1 region with 2 zones. And I found only metadata is replicated, the data is NOT. According to your check list, I am sure all thinks are checked. Could you review my configuration scripts? The configuration files are similar to
http://docs.ceph.com/docs/master/radosgw/federated-config/. 1. For the master zone with 5 nodes of the region (1) create keyring sudo ceph-authtool --create-keyring /etc/ceph/ceph.client.radosgw.keyring sudo chmod +r /etc/ceph/ceph.client.radosgw.keyring sudo ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.us-east-1 --gen-key sudo ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.us-west-1 --gen-key sudo ceph-authtool -n client.radosgw.us-east-1 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring sudo ceph-authtool -n client.radosgw.us-west-1 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.us-east-1 -i /etc/ceph/ceph.client.radosgw.keyring sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.us-west-1 -i /etc/ceph/ceph.client.radosgw.keyring (2) modify Ceph cluster configurations and synchronize it ceph-deploy --overwrite-conf config push node1 node2 node3 node4 node5 (3) configure Apache (4) configure region sudo apt-get install -y radosgw radosgw-agent python-pip sudo radosgw-admin region set --infile /home/ceph/us.json --name client.radosgw.us-east-1 sudo radosgw-admin region set --infile /home/ceph/us.json --name client.radosgw.us-west-1 sudo rados -p .us.rgw.root rm region_info.default sudo radosgw-admin region default --rgw-region=us --name client.radosgw.us-east-1 sudo radosgw-admin region default --rgw-region=us --name client.radosgw.us-west-1 sudo radosgw-admin regionmap update --name client.radosgw.us-east-1 sudo radosgw-admin regionmap update --name client.radosgw.us-west-1 (5) create master zone sudo radosgw-admin zone set --rgw-zone=us-east --infile /home/ceph/us-east.json --name client.radosgw.us-east-1 sudo radosgw-admin zone set --rgw-zone=us-east --infile /home/ceph/us-east.json --name client.radosgw.us-west-1 sudo radosgw-admin zone set --rgw-zone=us-west --infile /home/ceph/us-west.json --name client.radosgw.us-east-1 sudo radosgw-admin zone set --rgw-zone=us-west --infile /home/ceph/us-west.json --name client.radosgw.us-west-1 sudo rados -p .rgw.root rm zone_info.default sudo radosgw-admin regionmap update --name client.radosgw.us-east-1 sudo radosgw-admin regionmap update --name client.radosgw.us-west-1 (6) create master zone’s users sudo radosgw-admin user create --uid="us-east" --display-name="Region-us Zone-East" --name client.radosgw.us-east-1 --system --access_key=us_access_key --secret=us_secret_key sudo radosgw-admin user create --uid="us-west" --display-name="Region-us Zone-West" --name client.radosgw.us-west-1 --system --access_key=us_access_key --secret=us_secret_key (7) restart Ceph & apache2 & radosgw services 2. For the secondary zone with 5 nodes of the region (1) copy the keyring file 'ceph.client.radosgw.keyring' from master zone and import the keyring sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.us-east-1 -i /etc/ceph/ceph.client.radosgw.keyring sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.us-west-1 -i /etc/ceph/ceph.client.radosgw.keyring
(2) modify Ceph cluster configurations and synchronize it ceph-deploy --overwrite-conf config push node1 node2 node3 node4 node5 (3) configure Apache (4) copy infile '/home/ceph/us.json' for the master zone and create 'us' region sudo apt-get install -y radosgw radosgw-agent python-pip sudo radosgw-admin region set --infile /home/ceph/us.json --name client.radosgw.us-east-1 sudo radosgw-admin region set --infile /home/ceph/us.json --name client.radosgw.us-west-1 sudo radosgw-admin region default --rgw-region=us --name client.radosgw.us-east-1 sudo radosgw-admin region default --rgw-region=us --name client.radosgw.us-west-1 sudo radosgw-admin regionmap update --name client.radosgw.us-east-1 sudo radosgw-admin regionmap update --name client.radosgw.us-west-1 (5) create secondary one sudo radosgw-admin zone set --rgw-zone=us-east --infile /home/ceph/us-east.json --name client.radosgw.us-east-1 sudo radosgw-admin zone set --rgw-zone=us-east --infile /home/ceph/us-east.json --name client.radosgw.us-west-1 sudo radosgw-admin zone set --rgw-zone=us-west --infile /home/ceph/us-west.json --name client.radosgw.us-east-1 sudo radosgw-admin zone set --rgw-zone=us-west --infile /home/ceph/us-west.json --name client.radosgw.us-west-1 sudo rados -p .rgw.root rm zone_info.default sudo radosgw-admin regionmap update --name client.radosgw.us-east-1 sudo radosgw-admin regionmap update --name client.radosgw.us-west-1 (6) create secondary zone’s users sudo radosgw-admin user create --uid="us-east" --display-name="Region-us Zone-East" --name client.radosgw.us-east-1 --system --access_key=us_access_key --secret=us_secret_key sudo radosgw-admin user create --uid="us-west" --display-name="Region-us Zone-West" --name client.radosgw.us-west-1 --system --access_key=us_access_key --secret=us_secret_key (7) restart Ceph & apache2 & radosgw services Any help would be much appreciated.
